John R. Lawrence
Current research and/or projects
Contributing to Environment Canada’s mandate: risks to Canadians and their environment posed by pollutants or other harmful or dangerous substances are assessed and aquatic ecosystems are conserved and protected
- Analyses of the fate and effects of emerging contaminants on microbial communities.
- Micro-scale and molecular techniques for assessing fate and effects of contaminants and other stresses on microbial communities
- Ecotoxicology effects of complex mixtures and municipal sewage effluents on aquatic ecosystems.
- Effects of pharmaceuticals and personal care products on ecosystem function
- Development of DNA microarrays for environmental effects monitoring including impacts of stresses on microbial community structure, function and biodiversity
